I am having trouble with all the emails coming from my new HostGator VPS being sent to user's spam folder. This is all outoging mail, including messages sent from sendmail (system notifications) and those sent from email accounts. Any mail (from any domain) that is sent from this VPS is going to the spam folder on Gmail, Yahoo, and Hotmail accounts. I have checked, and the domains and IP address of the server are not blacklisted anywhere (that I can find). I do not have the expertise to diagnose this problem, and Hostgator support is not able to solve it either.
